Overview

To help you keep up with ever-growing security challenges, SAP NetWeaver 7.40 includes a new framework, Unified Connectivity (UCON), for securing Remote Function Calls (RFCs). RFCs are a central communication technology of SAP NetWeaver Application Server ABAP and all ABAP-based systems.

The UCON basic security scenario for RFC provides both a simple process and a toolset allowing you to drastically reduce the number of Remote-Enabled Function Modules (RFMs) that can be accessed from outside, thus dramatically reducing the potential attack surface. UCON is the new approach you should choose to make your RFC communication more secure.
